HEALTH WATCH

Body Watch

Children don't always know that they're having trouble seeing, so it's up to you to watch for signs of poor vision. For example, you might catch your child squinting or turning his or her head in an unusual manner to watch television. Also, the child might be disinterested in looking at distant objects or in reading books.

"Children with a vision problem will not complain," says Dr. Susan H. Day, a pediatric ophthalmologist in San Francisco. "Very early detection of treatable eye disease often leads to more effective and less expensive treatment and may enhance your child's ability to learn."

Children should have an eye exam by age 5, according to the Academy of Ophthalmology. Their most common eye problems are:

* Strabismus, a misalignment of the eyes causing them to point in different directions. (Treatment involves eyeglasses or a patch over the strong eye; sometimes surgery is necessary.)

* Amblyopia ("lazy eye") in which vision does not develop normally during childhood. (Treatment includes glasses and a patch over the strong eye.)

Summer is on the wane, but there's still plenty of time for bug bites and the usual summertime ouchies. Typical summer injuries are cuts, scratches and skin irritants such as insect bites and sunburn, says Fred Weissman, USC associate professor of clinical pharmacy.
